Every Shell can carry every weapon, so your primary is the one build decision nothing later takes back off you. Here is our order for all 8, ranked on the two things that actually separate them — the ability each carries, and how much of the Tarstone collection it can hold, which runs from 19 stones to 25.
Ranked as of Balance Patch 1, August 21, 2026. Every balance change we hold is on the patch log, so you can see what has moved since.
How this list is ranked
Start with what is not a difference. All 8 primaries run the same Tarforge ladder — the same materials, the same Coin and the same damage curve, rung for rung, all the way to +16. We checked that when we priced every rung, and it is checked again on every build. So no weapon here is cheaper to take to the cap than any other, and “it scales better” is not an argument anybody can make about this rack.
What is left is the ability and the stone pool, and we weight them in that order. The ability is a move you cannot get anywhere else and it is what you build around; the pool decides how much of your collection the weapon can use, which matters more the longer a run goes. Primaries take between 19 and 25 stones, and 14 of those go in all 8 — so the spread that actually separates one weapon from another is the 6 stones between the smallest pool and the largest, not the totals themselves. Every count on this page is the same count: the number of stones whose own compatibility list names the weapon.
The third factor is when you can hold it, and it is the reason two weapons with similar kit are a band apart: a very good weapon carried from Gloomshade Grove beats a marginally better one you reach in Mammon. Finally, one weapon here have no ability recorded by either source we hold. That caps how high we will rank it, and the verdict says so rather than pretending the gap is a weakness.
The Tarstones column is the count of stones that name this weapon as compatible — the game's answer rather than ours, inverted out of each stone's own list, and the same figure the compatibility chart shows. If you are working the other way round, from a stone you already have to the weapons that take it, the compatibility chart is the whole matrix in one grid.
SWhich are worth building a run around?
Worth restructuring a playthrough to get hold of, and worth keeping once you have.
Black NeedleS
Stolen from the Twiceborn, this spear enables the bearer to reach further and more quickly than seems physically plausible.
Ability
Needle Storm
Compatible Tarstones
25
Where it is
Map purchased from merchant
Every primary shares one upgrade ladder, so a weapon ranking is a question about kit and stone pool and nothing else — and this one has the deepest pool in the rack. Twenty-five compatible Tarstones on a spear that already outreaches the rest means the Black Needle can use more of your collection than any other choice, for longer. If you intend to re-tune one weapon for the whole run, re-tune this one. The Sesters drop it and a merchant sells its map, so there are two roads to it rather than one.
A two-handed sword, achingly cold to grasp. A remnant from a long dead empire. The First Martyr reserved this greatsword for heretics, but the blade fell upon many pious necks. In time devotion was not enough, the Enshrined whispered of new sins and new foes hidden within their ranks.
Ability
Spiral Surge
Compatible Tarstones
23
Where it is
Martyr's Prison, Gloomshade Grove
Twenty-three compatible stones is near the top of the range, and the reason this ranks with the Black Needle rather than beneath it is when you can hold it: Martyr's Prison is in Gloomshade Grove, comfortably inside the first half of a run. A very good weapon you carry from there to the end beats a marginally better one you only pick up in Mammon. Spiral Surge is what you take it for.
No argument against taking one of these. Which you take depends on what you want to be doing.
Obsidian HammerA
A brutalist chunk of obsidianite, profaned by bloodshed beyond the Seat of Infinity.
Ability
Heavy Stomps
Compatible Tarstones
24
Where it is
Obsidianite Mines, Mammon
Twenty-four compatible stones on the heaviest thing you can carry, second only to the Black Needle, and Heavy Stomps points at the crowds a weapon this size wants to be in anyway. It ranks below the two above on timing rather than on kit — it is at the bottom of the Obsidianite Mines in Mammon, which is the second half of the game and a long way to carry something else.
An unusual pairing of a simple thieve's tool and a vicious axe from the northern lands.
Ability
Deadly Flurry
Compatible Tarstones
19
Where it is
Mushroom Village Gate Beacon
The fewest compatible stones of any primary — six behind the Black Needle — and it matters far less than the number suggests. This is a paired set built on the light string, and one of only two primaries the Duality Stone fits, which strikes that string twice: on a bar that fills per hit landed rather than per second, that is your Resolve income doubled on the weapon that was already earning fastest. Income beats six more stones you were not going to socket. It is also one of the earliest primaries a run can reach, which buys it a great deal of use.
Its ability is a chainsaw, and sustained contact damage is genuinely rare in a game built around discrete, punishable swings. Twenty-one compatible stones is below the middle of the range, but it is the one primary with something close to a dedicated build attached — it takes the Clockwork Shardstone and the Scholar's Wormstone, and no other weapon takes either — so that pool goes further than the count implies. Two records reach it: Merrick sells the map, and Sariel the Endless drops it.
Real strengths and a real condition attached. Excellent where it fits, ordinary where it does not.
The IconoclastB
Exceptionally light for a two-hander, it was once held by a seedbearer of great renown.
Ability
Plummet Strike
Compatible Tarstones
22
Where it is
Prologue Area
Twenty-two compatible stones is mid-pack rather than starved and a two-hander this light is a genuinely good default, which is exactly the problem with ranking it higher. Everything good about The Iconoclast is that it has nothing to learn around, and a weapon with nothing to learn around is one you outgrow rather than one you build toward. It costs you nothing and it is waiting when the prologue ends.
A pair of twin blades, crafted to transform into an axe. An exquisite invention of unknown origin. The twin-blades are notable in their own right, but the mechanism by which they combine offers up near infinite possibilities in battle.
Ability
Morph Attack
Compatible Tarstones
20
Where it is
Location Map purchased from Merrick
Morph Attack is the only ability in the rack that changes the weapon's shape inside a single string — twin blades for speed, axe for weight — and that is a real option nothing else sells. Twenty compatible stones is the second-smallest pool, though, and the location map is a purchase from Merrick rather than a thing you walk into, so this is a deliberate detour for a weapon that asks you to learn a second moveset once you get there.
CWhich come with a real cost, or too little on record?
A trade-off you have to accept, or a gap in what anybody has written down that we will not rank past.
Veteran's Battle AxeC
This solid steel axe is rumored to have been quenched in the blood of the Revered.
Compatible Tarstones
23
Where it is
The King's Crypt dungeon, Blackridge Cliffs
Twenty-three compatible stones is a top-half pool, and it is nearly the only figure there is to rank on: neither source we hold records this weapon's ability at all. That is a gap in the documentation rather than an axe without a move, so read C as where our argument stops rather than where the weapon does. The one thing the record does give it is exclusive — the Inflamed Clawstone fits no other primary — which is a reason to carry it that has nothing to do with the empty field. It is at the bottom of The King's Crypt, a side trip with a dungeon attached.
No, and the ladder is why. Taking every primary to +16 costs 8 times what taking one there does, and because the curves are identical, the second weapon buys you a different move rather than a better number. Pick the move you want to build around, feed it everything, and treat the rest of the rack as things to try before you commit rather than things to keep pace.
Which move to build around is what the build guides argue, one loadout at a time — and each of them names the Tarstones that fit the weapon it recommends, checked against that weapon's own compatibility list.
